SASH-FASTEIN'ER.

raeaios.

To all whom it may concern:

Be it known that I, KORNAKIGHI HORI- KAWA, a subject of the Emperor ofJapan, residing at Seattle, in the county of King and State ofWVashington, have invented a new and useful Improvement inSash-Fasteners, of which the following is a specification.

This invention relates to improvements in window sash fasteners and theobject of this improvement is to provide a relatively cheap and simplesash fastener of strong and durable construction that is neat inappearance and easy to install on any ordinary window.

A further object is to provide a sash fastener that may be quickly andeasily operated to lock the two sashes of a window and prevent movementthereof either when they are closed or in any open or partially openposition.

Still further objects are to provide a fastener that requires only onescrew to rigidly secure it to the windowsash and one wherein the screwmember will lie close to the window sash and be covered by a portion ofthe sash fastener frame.

The invention consists in the novel construction, adaptation andcombination of parts as will be more clearly hereinafter described andclaimed.

In the accompanying drawings Figure 1 is a fragmentary view inperspective of a double sash window upon which my fastener is installedand Fig. 2 is a view in perspective of the sash fastener apart from thewindow.

Referring to the drawings throughout which like reference numeralsindicate like parts the numeral 5 indicates a window frame and 6 and 7are upper and lower window sashes respectively of well known form thatare adapted to slide vertically between suitable stops 8 in the windowframe.

This fastener comprises a one piece frame or supporting member that ismade up of a longer leg 9, a top portlon 10 and a shorter leg 11 andpresents somewhat the appearance of an inverted letter L when viewed inside elevation.

The longer leg 9 is provided with a countersunk screw hole 12 and theshorter. leg 11 terminates in an integrally formed barb 13.

thumb engaging element 15 on one end and a pivotally mounted washer orsash engaging plate 16 on the other end.

The spindle 14 passes loosely through a suitable hole in the longer legmember 9 and is screwed through a similar hole in the shorter leg member11 so that it lies closely beneath the top plate 10 and close to the topof the sash 7 and does not occupy much room.

The fastener may be quickly and easily secured on a window sash bydriving the barb 13 into the top of the sash and then inserting a screw17 as shown in Fig. 1.

The two sashes are locked in any desired open or closed position byscrewing the washer 16 tightly against the sash 6 thus causing the twosashes to securely bind against the stops 8 and be locked against anyforce tending to open or close them.

The device thus provides an easy and simple means of securing a desiredamount of ventilation and at the same time prevents burglars and thelike from opening the window from the outside sufliciently to gainadmission to the house.

This device is also particularly useful in preventing window sash thatare loose in the window frame from rattling when the wind blows.

I am aware that window fasteners of a similar nature to mine havepreviously been made but so far as I know none of these have attainedthe simple construction, neat appearance, ease of installation andstrength of the present device.

This fastener is made up of three pieces namely the frame member thethreaded spindle and the sash engaging washer and can be rigidly securedto the window sash by a single screw. Moreover it will be noted that thespindle 14L lies very close to the top of the sash 7 so that the thrustapplied through the screw has very little tendency to pry the fastenerframe off of the sash and that the thrust is practically all sustainedvice may be resorted to within the scope of r the appended claim.

What I claim and desire to protect by Letters Patent is:

The combination with a window having an upper and a lower sash of a sashfastener comprisingan integral L shaped frame sald frame having a longerleg adapted to extend downwardly over the side of said" lower sash, ashorter leg adapted to rest 1115611: the top of said lower sashand a topportion connecting said two legs, a barbon said shorter leg portion toproject into the top of said sash, a screw threaded spindle extendingthrough said leg portions and disposed between the top of said lowersash and-the top portion of said frame and a washer swiveled on theouter end of said spindle to engage with said upper sash andfri'otionally lock said two sashes.
